“…Ignoring forest functions will make it difficult to assess, adapt, and reduce the impacts of forest land cover and climate change [250]. Another opinion also suggests that land cover (including forest) is one of the determinants of regional water yields [251]. As a regulator of the water system, the forest serves one of its ecological purposes.…”

Indonesia is the largest archipelagic country in the world, with 17,000 islands of varying sizes and elevations, from lowlands to very high mountains, stretching more than 5000 km eastward from Sabang in Aceh to Merauke in Papua. Although occupying only 1.3% of the world’s land area, Indonesia possesses the third-largest rainforest and the second-highest level of biodiversity, with very high species diversity and endemism. However, during the last two decades, Indonesia has been known as a country with a high level of deforestation, a producer of smoke from burning forests and land, and a producer of carbon emissions. The aim of this paper is to review the environmental history and the long process of Indonesian forest management towards achieving environmental sustainability and community welfare. To do this, we analyze the milestones of Indonesian forest management history, present and future challenges, and provide strategic recommendations toward a viable Sustainable Forest Management (SFM) system. Our review showed that the history of forestry management in Indonesia has evolved through a long process, especially related to contestation over the control of natural resources and supporting policies and regulations. During the process, many efforts have been applied to reduce the deforestation rate, such as a moratorium on permitting primary natural forest and peat land, land rehabilitation and soil conservation, environmental protection, and other significant regulations. Therefore, these efforts should be maintained and improved continuously in the future due to their significant positive impacts on a variety of forest areas toward the achievement of viable SFM. Finally, we conclude that the Indonesian government has struggled to formulate sustainable forest management policies that balance economic, ecological, and social needs, among others, through developing and implementing social forestry instruments, developing and implementing human resource capacity, increasing community literacy, strengthening forest governance by eliminating ambiguity and overlapping regulations, simplification of bureaucracy, revitalization of traditional wisdom, and fair law enforcement.

Hydrology is one of the criteria for monitoring and evaluation (monev) of watersheds management as stated in the Minister of Forestry Regulation Number P.61/Menhut-II/2014. So far, the use of various hydrological parameters for the monev of watersheds has not been evaluated whether these parameters truly reflect the condition of the watershed. This study aimed (1) to evaluate the effect of rainfall on the hydrological criteria of each sub-watershed, which include: flow regime coefficient, annual flow coefficient, sediment load, and water use index and (2) to evaluate the effect of rainfall on watershed carrying capacity. Regression analysis was used to see the relationship between annual rainfall and hydrological parameters used in watershed sustainability. This analysis was crucial to see the development of forest and land rehabilitation efforts in restoring degraded land. Data collection was carried out from 2008 to 2016 in each of the sub-watersheds of the Citanduy Watershed, namely Cijolang, Cikawung, Cimuntur, Ciseel, and Upper Citanduy. From this research, it is known that flow regime coefficient, annual flow coefficient, sediment load, water use index, and flood frequency are strongly influenced by rainfall so the result in evaluating watershed carrying capacity may vary depending on the rainfall. Besides being influenced by rainfall, flow regime coefficient, annual flow coefficient, and sediment load are also affected by land cover, while the slope affects the sediment load.

“…Peranan penutupan lahan sangat penting dalam menentukan jumlah debit sungai yang dihasilkan. Dinamika lahan secara kualitas dan kuantitas, baik penggunaan maupun penutupan lahan mengakibatkan perubahan pada hasil air dalam DAS (Basuki et al, 2017;Nugroho et al, 2013;Quyen et al, 2014;Sun et al, 2017;Muchtar & Abdullah, 2007). Lebih lanjut penutupan lahan merupakan faktor penting yang memengaruhi tanah longsor yang dipicu oleh intensitas curah hujan tinggi (Hasnawir et al, 2017).…”

The biogeophysical characteristics of watersheds have an important role as a determinant of the river discharge amount in the watershed. Various watershed problems such as flood and drought related to river discharge require data and information. The importance of this data and information will determine a better watershed management plan. The issue of flooding and drought are the important issues in Ralla sub watershed, Souht Sulawesi Province. This study aims to describe the biogeophysical characteristics and the discharge of Lompo Riaja Atas and Lompo Riaja Bawah Rivers in Ralla sub watershed, Lisu Watershed. This research was conducted in from November 2016 to August 2017. Primary data collection was done through river discharge and precipitation measurements during 34 days of observation. Secondary data obtained from government or related agencies such as geological data obtained from Geological map of the Ujung Pandang sheet 1982, the slope data from Aster DEM, land type from RePPProt 1987, land cover data from google earth image 2015. A quantitative descriptive method was used to analyze the data obtained. The results showed that the Lompo Riaja Atas and Lompo Riaja Bawah rivers have relatively similar discharge fluctuation, although they have a different amount of discharge. River discharge of both rivers is more influenced by rainfall compared to biogeophysical conditions such as geology, topography, soil type, watershed area, watershed shape, river length and order, gradient, flow pattern, flow density, and land cover.
